BUTTON-DIE.

SPECIFICATION forming part of Letters Patent No. 475,476, dated May 24,1892.

Application filed December 2, 1891. Serial No. 413,811. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES WAcnNFoHn, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain newand useful Improvements in Button-Dies; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to whichitappertains to make and use the same.

This invention relates to a machine for making buttons; and it has forits prime object the provision of a sleeve or cutter having a spiralmovement for cutting off the overflow after a button has been shaped orformed.

A further object of the invention is to accomplish by such movement ofthe sleeve or collar a ready release or droppingof the button from theupper die.

Other objects and advantages wi 11 appear from the following descriptionand claims, when taken in connection with the annexed drawings, inwhich- Figure 1 is a vertical central sectional view of a pair of dieswith my improved spirallymovable sleeve or cutter in position to beoperated in connection with any suitable press. Fig. 2 is a side view ofthe same. Fig. 3 is a vertical diametrical sectional View of the sleeveor cutter, illustrating a modification. Fig. t is a view of the upperdie,part-ly in section. Fig. 5 is a detail sectional view of the lowerdie; and Fig, 6 is a perspective view of one end of the upper die,illustrating a design which may be used when it is desirable to ornamentor embellish the face of the buttons.

Before describing the details of construction which I have illustrated Iwish to state that although I have here shown a pair of dies and otherparts of a machine of a character which I prefer to employ, yet I do notwish to be understood as confining myself to the particular constructionof devices which I have here shown and shall presently describe, as I amaware that various modifications might be made in the parts and the diesmay be used in a press of any ordinary or approved construction; but Iattach great im portance to the employment of a spirallymovable cuttingcollar or sleeve, or a sleeve or collar from which a spiral cutting move1nent-such as that received from rotary shears-might be obtained.

Referring by letter to said drawings, A indicates the bed plate orblock, which is provided with a central vertical screw-tapped aperturea, and above this aperture is mounted the lower-die holder B, carryingthe lower die 0, which is provided with a concave face Z) and a slot 0to receive the shank of a button. This lower-die holder, which isprovided with a vertical aperture d, is also screw-tapped, as shown atc, to receivethe upper reduced and threaded end f of a bolt D, wherebysaid die and its holder may be secured to the bed of the press.

E indicates the head of the press, which is here shown as of a block ofmetal having a vertical screw-tapped aperture g.

F indicates the upper-die holder or body. This body, which is ofcircular form in outline or cross-section, is provided with ascrewtapped aperture h and afurther screw-tapped aperture t of a lessdiameter. The first screwtapped aperture h is designed to receive thelower end of a threaded and headed bolt G, which is designed to connectsaid die holder or body with the head-block E, while the lower threadedaperture t is designed to receive the externally-threaded shank 7c ofthe upper die II. This body or holder F is also provided externally witha spiral groove or grooves, as shown, and while I do not wish to confinemyself to any particular form of groove, yet I prefer a square-cutgroove or one in which the walls are rectangular, such as illustrated inFig. 1 of the drawings.

I indicates the cutting collar or sleeve. This collar is providedvertically for a sufficient portion of its length with a planed andsmooth bore Z for the reception of the upper die, and above said borethe collar is provided internally with spiral grooves or projections toenter the grooves in the body F, and vice versa, so that when anoscillating or rotary motion is imparted to the collar by the hand orotherwise said collar will ride down over the body F, and consequentlythe cutting-edges of the dies, in a spiral manner, and when the motionof the collar has been reversed said collar will rise in areversedmanner. By the first movement a rotary shear-cut will be given to thematerial-such as rubber, melted glass, or the like fed between the diesin the usual manner-from which the button has been formed, so as toeffectively cutoff the overflow, while the second or reverse movement ofthe collar after the dies have been separated will cause the buttonafter it has been formed to drop from the concavity of the upper die.

L indicates alever secured todthe spirallymovable collar, whereby thesame may be manipulated by hand or otherwise.

may, instead of having a spiral groove or proect-ion on the body providethesame with a stud or lug m to enter the spiral groove in the sleeve F,or vice versa, and His obvious that this spiral movement of the collarmay be obtained by various other means without departing from the spiritof my invention.

By reference to Fig. 6 of thedrawings it will be seen that I haveengraved a design upon the operating-face of the upper die, as such isdesirable when the face of the but-. tons are to be embellished orornamented.

Having described my invention, what I.

' claim is the dies and adapted to move back andforth As onemodification of my improvement'I or up and down over the meeting edgesof both dies, substantially as specified.

2. In a machine for making buttons, the combination, with the upper dieand a lower die, of a body or holder having an externallyspiral grooveor projection and a sleeve or col- Llar for said upper die. engagingsaid groove or projection, so as to receive a spiral motion,

(substantially as specified.

3. The combination, with alower die, of the upper die having thethreaded shank, the

body or holder having an internally-threaded aperture to receive saidshank and an exter- ,nal spiral groove or projection, and the sleeve orcollar having an internally-planed aperture to receive the die'and aninternally-spiral ,groove or projection toengageandco-operate with acorresponding surface on the holder or body, so as to impart a spiralmotion to said sleeve when turned on the die, substanftially asspecified. i In testimony whereof I aflix my signature in presence oftwo witnesses.
